What term describes the angle between the bevel of a joint member and a plane perpendicular to the surface?

• A. Groove angle
• B. Bevel angle
• C. Fillet angle
• D. Draft angle

Answer: (B)

Bevel angle describes how steeply the edge of a joint member is cut relative to the plane that is perpendicular to the surface. In sheet metal joints, you bevel the edge to create a prepared face for welding, and the bevel angle is the measure of that tilt from the surface normal (the line perpendicular to the surface). This angle directly influences weld access, penetration, and fit-up. Other terms describe different things: the groove angle refers to the angle inside a groove between the mating faces, draft angle is the taper used to release a part from a mold, and fillet angle isn’t a standard term for describing the bevel orientation of a joint edge.
